I have a new computer and just installed Thunderbird so I could use it for an existing account. I used Thunderbird on my old computer and wanted to keep using it on my new computer. Upon installation I initiated an automatic imap account setup. Thunderbird found the correct setting but when I attempt to save the configuration it comes back with an error message "incoming server already exists". See the screen shot below. Any help on this will be appreciated. Kiteboarder.
